The aim of this project is to investigate some significant changes in the worlds social, and economic landscape from 1960 till now. Following aspects are taken into consideration:
The data used in this report is collected from gapminders.com which aggregated from different sources (WHO, WorldBank,…) otherwise stated.
Lets see how the world’s population has grown over past decades as well as World Bank’s projection till 2050.
It can be seen that the population has increased quite alot since 1960s till now and continue to grow to 2050s. However, the trend has been slow and its is projected that the total population will start to shrink afterward. To support this claim, we will investigate in further steps.
A glance at the distribution of population around the world
Two most populated countries are China and India which is not surprising at all. Next comes USA, Brazil,..
It can be seen that there is a significant change in the age structure of the world’s population from 1960s to 2017 across all continents especially in Asia. There now more and more people living more than 70 years old. This may due to a great improvement in health care. This is one of the important factor driving the number of total world’s population.

The wolrd’s population distribution (right hand sight) shows that the most populated countries in the world are India and China; however, the fertility rate is SMALL now, especially in China. The number of baby per women is 1.63 (which is under 2.1 - the fertility rate to keep total population stable). India with a fertility rate of 2.3 will witness a positive population growth next few decades; however the trend is going down and it may approach the long term stable population growth.
Some may claim that the number of babies per women is strongly affected by the religion they follow. We cant completely reject this claim; however, we doubt if there is the only reason. It can bee seen that the trend of declining fertility rate is consistent across all religions (while there is no fundamental changes in these religions, I guess). Hence, there should be another more important factor affecting fertility rate other than religion. We will get back to this after analyzing other factors.
It can be seen that richest countries are European and North American.
Lets see the trend of economic development along with other indicators in latter step.

Above chart, show the life expectancy and Gdp per capita accross all countries in 1960 and in 2017. Two important observations:
=> People live longer and richer
However, it would be better to see how they progress overtime, so please see the arnimation in the Script. Below is the screen shot of the visualisation.
l1
China did a great job in increasing their GDP per capital form 1960 to 2017.

Above charts show two static snap shot of relationship between child mortality and fertility rate in 1906 vs 2017. They definitely have a positive correlation. Below is the animation showing how the relationship changes overtime.
l2
It can be seen that there is a strong correlation between child mortality and child fertility rate. People give birth more when they are not sure if their child can survive !!. The size of the buble shows the wealth of each country (gdp per capita). It suggest that not only in rich country, but in poor country, people give birth less as long as their child has a higher chance to survice.
A glance at the distribution of literacy rate around the world in 2000 vs 2017

Literacy rate is increasing around the world especially in Africa. For example Literacy rate in Sudan increased from 61% to 71.9% from 2000 to 2017.

Due to lacking of data, we cant compare the change in major countries. There are two important notes:
Although there are lots of social problems now; we live in a much better world than 70 years ago!!!!!
